Specs come from AMD documents, motherboard CPU support lists and other open sources and may contain errors. AMD often sold one model number on several cores and revisions, so check the OPN code printed on the CPU before buying: its last letters give the revision. The search box also finds OPN codes, but our OPN lists are not exhaustive.

Socket 939 vs 754, 940 and AM2

AMD launched Socket 939 in June 2004 to bring the dual-channel memory of its server platform to desktops without the expensive registered RAM. The memory controller sits inside the CPU, so the socket defines the memory: two channels of ordinary unbuffered DDR (DDR1). Every 939 processor supports AMD64 and the NX bit. In May 2006 the platform was replaced by AM2 with DDR2.

Socket Since Memory Processors
754 2003 DDR, single channel Athlon 64, Sempron
940 2003 DDR, dual channel, registered ECC Opteron, Athlon 64 FX-51 and the first FX-53
939 2004 DDR, dual channel, unbuffered Athlon 64, X2 and FX, Opteron 1xx, Sempron
AM2 2006 DDR2, dual channel Athlon 64, X2 and FX, Sempron, Opteron 1200

None of these sockets accepts a CPU from another. AM2 also has 940 pins, but it isn’t compatible with Socket 940. A model number doesn’t tell you the socket either: an Athlon 64 3200+ or an X2 4200+ exists for 939 and for AM2, so check the OPN. On 939 chips the character right after the model number is a D: ADA3200DAA4BW. The 939 Opterons also use ordinary unbuffered DDR and run in desktop boards, unlike their Socket 940 counterparts. The next generation is covered in our AM2 and AM2+ CPU list.

Cores and revisions

Behind the same model numbers sit three generations of the K8 core. Revision decides two things that still matter: SSE3 support and how well the memory controller copes with four modules.

  • CG, 130 nm: ClawHammer and Newcastle. The 2004 launch chips. ClawHammer is the 1 MB L2 die (the 4000+, FX-53 and early FX-55; the 3500+ and 3800+ have half the L2 switched off), Newcastle has 512 KB. No SSE3.
  • D0, 90 nm: Winchester. The first 90 nm Athlon 64 (3000+, 3200+, 3500+), cooler at 67 W. Still no SSE3, and the same goes for a rare D0 version of the Sempron 3000+.
  • E, 90 nm: Venice, San Diego, Manchester, Toledo, Palermo, Venus and Denmark. The chips launched from 2005 on. Venice and San Diego are the single-core Athlon 64 with 512 KB and 1 MB of L2, Manchester and Toledo are the dual-core X2 and FX-60, Venus and Denmark the single- and dual-core Opterons, Palermo the 939 Sempron. All of them have SSE3. A few late single-core Athlon 64s are dual-core dies with one core switched off, and the table lists them as separate rows.

SSE3 is the dividing line for software. Google Chrome has required it since version 89 (2021), so current Chrome doesn’t run on a ClawHammer, Newcastle or Winchester. Revision E also brought a better memory controller: four double-sided DDR400 modules run at full speed (with a 2T command rate), while CG and D0 chips usually drop to DDR333 with four modules. The new controller also handles different-sized modules on one channel and adds unofficial dividers above DDR400 if the BIOS exposes them.

The OPN tells you the revision. Its last two letters are the code. The common ones: AS, AW and AZ mean CG; BI means D0; BP means E3; BN and BV mean E4; BW, CD and CF mean E6. The digit before them is the total L2 size: 2 for 128 KB, 3 for 256 KB, 4 for 512 KB, 5 for 1 MB, 6 for 2 MB. So ADA3500DAA4BW is a Venice E6 with 512 KB, and OSA165DAA6CD a dual-core Denmark.

Will it run in my board?

  • BIOS. Revision E and especially the dual-core chips (X2, FX-60, Opteron 165–190) need a BIOS that supports them. Update the BIOS before you swap the CPU. If the current BIOS already supports single-core revision E chips, you can usually flash a dual-core BIOS with the old CPU installed. If it doesn’t, you may need a chip the current BIOS already knows, such as a borrowed CG or D0 Athlon 64, just to do the flash. The board maker’s CPU support list is the best guide.
  • Chipset. AMD’s official 2005 dual-core list covered nForce4, nForce4 Ultra and SLI, VIA K8T800 Pro and ATI Xpress 200. nForce3 boards got dual-core support late and only from some makers. The first revision of VIA K8T890 didn’t support dual-core properly, which is why the ASUS A8V-E Deluxe is known for lacking X2 support while the later A8V-E SE has it.
  • Graphics slot. Early 939 boards are AGP, later ones PCIe, and boards with the ULi M1695 and M1567 chips, such as the ASRock 939Dual-SATA2, have both slots (only one works for graphics at a time).
  • Power. The fastest chips are rated 104 W (FX-55, FX-57, Opteron 152–156) and 110 W (X2 4400+, 4600+ and 4800+, FX-60, all dual-core Opterons). Check that the board’s CPU list names the exact model, since the X2 4400+ also exists as an 89 W part.
  • Memory. Unbuffered DDR only, officially up to DDR400. Registered server memory doesn’t work.
Chipset Graphics HyperTransport
nForce3 250Gb AGP 800 MHz
nForce3 Ultra AGP 1000 MHz
nForce4, Ultra, SLI, SLI X16 PCIe 1000 MHz (some early nForce4 boards 800 MHz)
VIA K8T800 Pro AGP 1000 MHz
VIA K8T890 PCIe 1000 MHz
ATI Xpress 200, CrossFire Xpress 200 PCIe 1000 MHz
ULi M1689 AGP 1000 MHz
ULi M1695 + M1567 PCIe and AGP 1000 MHz
SiS 755FX / SiS 756 AGP / PCIe 1000 MHz

Which CPU to choose

  • Fastest realistic upgrade: the Opteron 185 or the FX-60. Both are dual-core at 2.6 GHz with 1 MB of L2 per core, and the FX-60 adds an unlocked multiplier. The Opteron 190 at 2.8 GHz is faster, but it was sold in very small numbers.
  • One step down: the Opteron 180 or the Athlon 64 X2 4800+, both 2.4 GHz with 2 × 1 MB. An X2 with 512 KB per core (3800+, 4200+, 4600+) is a bit slower at the same clock, but the 3800+ and 4200+ are 89 W chips that suit weaker boards.
  • For overclocking: the Opteron 165, 170 or 175. They have 1 MB of L2 per core and low stock clocks, and on air they typically reach 2.6–2.8 GHz. The multiplier can only go down, so you overclock through the reference clock: the 165’s 9× needs around 300 MHz, which takes a good board, and the HT multiplier has to be lowered. Only the FX chips are unlocked; AMD’s Black Edition series came later, on AM2.
  • Board without dual-core support: a single-core revision E chip. The fastest are the Opteron 156 at 3.0 GHz and the FX-57 at 2.8 GHz; the San Diego Athlon 64 4000+ and 3700+ have the same 1 MB of L2 at 2.4 and 2.2 GHz.
  • CG and D0 chips: only if one comes with the board. Without SSE3 they are a dead end for modern software.
  • Sempron: rare OEM and regional chips with a small cache. A used Athlon 64 makes more sense.

FAQ

Which Windows runs on Socket 939?

The newest 64-bit versions that run are Windows 7 and the original Windows 8. The 64-bit editions of Windows 8.1, 10 and 11 refuse to install on every 939 CPU, the FX-60 and Opteron 185 included, because they require the CMPXCHG16B instruction, which AMD only added in the 2006 AM2 chips. The 32-bit editions of Windows 8.1 and 10 do run on all of them, limited to about 4 GB of RAM, but both are out of support: 8.1 since January 2023 and 10 since October 2025.

Does Linux still run on Socket 939?

Yes, on distributions that keep the original x86-64 baseline: Debian 12 and 13, the standard Ubuntu 24.04 and 26.04 images, Linux Mint 22, Fedora, Arch and openSUSE Tumbleweed. Distributions built for x86-64-v2 or higher, such as RHEL 9 and 10 with their clones and openSUSE Leap 16, won’t boot on any K8 processor.
